The Globe Models GL300T and GL300G Bronze Butterfly Valves are indicating type valves designed and Listed for use in fire protection systems. These valves are rated for a maximum working pressure of 300 psi (20 bar) and provide a visual indication as to whether the valve is open or closed.
They are provided with 2 sets of factory installed Form-C internal supervisory switches monitoring the valves in the normally open position. These supervisory switches transfer their electrical contacts within the first two revolutions of the handwheel towards the closed position.
The valves are available with female threaded end connections (GL300T) or grooved end connections (GL300G). The GL300T and GL300G are typically used as system indicating control/shutoff valves.
